Haiyan was called a super typhoon for part of its life because of it sustained winds of more than 150 mph. Wind speed, however, is not the only factor that determines the destructiveness of storms.
Because,yolanda typhoon with maximum sustained surface winds greather than or equal to 130 knots (approximately Category 5) is called a "super typhoon," and a hurricane of Category 3 and above is called a "major hurricane." A tropical cyclone weaker than Category 1 is not a "typhoon" in the international standard, but maybe..
